Answer:
3√r = k/s²
s²r^1/3 = k
Step-by-step explanation:
Cube root of r = 3√r
Square of s = s²
cube root of r varies inversely with the square of s
3√r = k/s²
Cross product
3√r * s² = k
s²r^1/3 = k
Note:
r^1/3
= 3√r

Answer:
DC = 21 ; BC = 26
Step-by-step explanation:
The perimeter of a rectangle is given by :
P = 2(length + width)
2x + 3
3x - 1
Perimeter, P = 94
Hence,
94 = 2(2x +3 + (3x - 1))
94 = 2(2x + 3 + 3x - 1)
94 = 2(5x + 2)
94 = 10x + 4
94 - 4 = 10x
90 = 10x
x = 90 /10
x = 9
DC = 2x + 3 = 2(9) + 3 = 18 + 3 = 21
BC = 3x - 1 = 3(9) - 1 = 27 - 1 = 26
x is greater than or equal to 6 so 5 and below are not a solution to this inequality.
